FUN: Sing a Song of Science

That wide-eyed paean to nuclear power comes from the “Ballads for the Age of Science” series of the late 1950s and early 1960s. At Science Songs, you can play more than 100 tracks from this earnest musical attempt to teach children about space, physics, weather, experiments, and nature. Software engineer Jef Poskanzer of Berkeley, California, exhumed six of the dusty albums from his parents' basement and put them on the Web. The songs may seem corny today, but Poskanzer says that listening to them “incessantly” as a child inspired his choice of career.
